# Before any interfaces are configured, we need to set the system
# default IP forwarding behavior.  This will be the setting for
# interfaces that don't modify the per-interface setting with the
# router or -router ifconfig command in their /etc/hostname.<intf>
# files.  Due to their dependency on this service, the IP forwarding services
# will run at this point (though routing daemons will not run until later
# in the boot process) and set forwarding flags.
